I have a 2019 F-350 Lariat with the power fold, heated, tow mirrors. I want to tie in some led running board lights. The running board lights have the courtesy on-fade off feature, along with constant on, and sequential turn signals. I need to find the parking lights wire, the ground wire, the turn signal wire, and the door assist light wire. There must be 20 different wires feeding into the mirror and I can’t find a current Ford wiring diagram to save my life. I will attempt to get a multimeter and check wire by wire if I need to, but I’m hoping someone has already attempted this and can name the four magic wires for me. Thanks!
